Error when trying to install or update package

[AdrianOlteanu]

Hi, I am getting an error when I'm trying to update or install the package with composer.

composer require kawankoding/laravel-fcm

[RuntimeException] Could not load package kawankoding/laravel-fcm in http://repo.packagist.org: [UnexpectedValueException] Could not p arse version constraint ~5.1.x: Invalid version string "~5.1.x"

[UnexpectedValueException] Could not parse version constraint ~5.1.x: Invalid version string "~5.1.x"

Thank you.

Same issue here!

Solved with a "composer self-update". Probably a composer bug...
